采用RP技术的玻璃模具的快速制造

对客户提供的玻璃器皿样品尺寸进行三坐标测量,利用RP技术可制得样品的树脂原型,利用石膏模和树脂原型制备模具毛坯的型芯,采用中空的毛坯木模来造型,可快速得到玻璃模具的毛坯;利用RP技术可制得模具电火花加工电极的树脂原型,利用ZrO2熔模铸造技术及有限元模拟技术,对型壳的焙烧过程进行模拟,优化型壳焙烧工艺方案,为电极的制备提供了依据。采用以上工艺,可实现玻璃模具的快速制造。

Glass mould's rapid manufacture based on RP technology

The glass service offered by client was measured in three coordinates dimensions,the RP technology was used to obtain colophony prototype of the specimen.The model core of mould’s roughcast was made using gesso mould and colophony prototype,using roughcast’s wooden model with a middle hole to molding,can rapidly achieve glass mould’s roughcast.The mould’s electric spark machining electrode’s colophony prototype was made using RP technology.Using ZrO2 molten mould foundry technology and finite element simulation technology,in order to simulate the model shell’s baking process,using this method can optimize technical scheme of model shell’s baking process and provide gist for electrode’s preparation.Using upper technology can achieve rapid making of glass mould.
